Title: Remote control device
IPC: H04B10/00
Filed: 1992-03-31
Abstract: PURPOSE:To enable a controlled equipment to deal with various installing conditions by transmitting an optical signal equivalent to a remote control signal. CONSTITUTION:The signal S1 sent from a remoted commander B is detected by a photodiode 2 and outputted to an amplifier circuit 3 after the photoelectric conversion. The circuit 3 consists of at least two stages where the gain is dsitributed. The first stage bias is amplified after the threshold value is set at a point near level 0, and the next stage bias is selected at a C-class action. Thus the noises of the input signals are eliminated together with the shaping of a waveform and the reduction of the power consumption as a whole. Then the next stage bias is amplified up to a desired voltage level and outputted. A drive circuit 4 has a switching operation with the output signal of the circuit 3 and converts a drive current into a near infrared ray to output an optical signal S2 equivalent to an input remote control signal. In such a constitution, the installing place of a remote control device A can be optionally selected together with a free attachment angle.
